test_steam_credentials

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. 'Test Steam API credentials' essentially restates the function name and adds no information about side effects, whether a network request is made, error behavior, or safety profile. It provides no behavioral value beyond what the name already implies.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence with no extraneous detail. It is appropriately sized for a no-parameter tool and front-loads the essential purpose. Every word earns its place, and the structure is optimal for quick agent parsing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (zero parameters) and has an output schema, so the need for a verbose description is low. However, the description does not explain when to run this test or what a successful or failed result implies, leaving some ambiguity about the tool's role in the broader credential lifecycle. It is minimally adequate but lacks contextual depth.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters and schema coverage is 100%, so the baseline for this dimension is 4. The description does not need to explain any parameters because there are none, and the empty schema fully documents the invocation contract.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action 'Test' and the resource 'Steam API credentials', making the tool's purpose immediately obvious. It also distinguishes itself from sibling test_* tools by naming the specific platform (Steam), so an agent can differentiate it without opening schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives. It does not mention typical scenarios (e.g., validating credentials before using other Steam tools) or exclude cases, leaving the agent to infer the intended usage entirely from the name and description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
